Just two things:
1) just because something is "harder" or "more difficult" doesn't mean it's hard or difficult. Just more so in comparison. So no there is no difference of definition of what difficult means.
2) objectively speaking, no one that I know of prefers a more difficult way of doing things on their smartphone. If there are its a rare and odd lot indeed.
1) Sometimes, people do have different definitions of difficult. For instance, you've said you don't like a physical home button and prefer gestures. I find that most gestures are (for me) harder to use than the home button.
2) I do, for example, prefer jailbreaking my iOS devices and using SBSettings or NCsettings and skip having to go to the Settings app to adjust various system settings. Those jailbreak tweaks are definitely easier than stock iOS. However, if something goes wrong with my jailbroken devices and I have to go back to stock, I wouldn't jump to Android -- not because I prefer doing things the "hard" way, but because for me, learning a different OS and having to find replacements for all the iOS apps I've accumulated would be a lot of trouble, so I'd rather put up with the minor (to me) inconveniences of stock iOS.
